Black courtesy phone? That's racist! /s
And a WHITE courtesy phone would not be? Actually, I thought of that when I wrote my reply. An example of how "Political Correctness" can drive our thought patterns. Maybe I should have said plaid (no that is too scottish), gold (no that is too plutocratic), pink (you guess), red (too political), maroon (sounds too moron-ish), brown (just kidding) ... The possibilities cover the spectrum, don't they!
